TROLLEY.

Specification of Letters Patent.

Patented Feb. 4, 1908.

Application Filed October 6. 1905- Serial No. 281578.

T all whom it may concern:

Be it known that I, JEAN E. SAUOIER, subject of the King of England, residing at Montreal, Province of'Quebec, Canada, have invented certain new and useful Improvements in Trolleys; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to vehicles which derive their propelling power from a wire charged with electricity; the object of my invention is to provide means whereby a constant current of electricity may be conducted from the wire to the car; a further object of my invention is to provide means to prevent breakage and wear of the wire caused by shocks received by the wire from the member which makes the connection between the wire and the car, and my invention consists of the construction, combination and arrangement of parts as herein illustrated, described and claimed.

In the accompanying drawings forming partof this application, I have illustrated one form of embodiment of my invention, in which drawings similar reference characters designate corresponding parts, and in which:

Figure 1 is a side elevation of the upper end of a trolley pole and a portion of a trolley wire, showing the application of my inven tion; Fig. 2 is aplan view; Fig. 3 is an enlarged plan of my invention detached; and Fig. 4 is a longitudinal vertical section through my invention detached.

Referring to the drawings, 5 designates an ordinary form of trolley pole, which is usually actuated upward by means of a spring, and which is provided with an ordinary form of trolley wheel 6, adapted to bear against the wire 7. Disposed on the pole 5 adjacent its end is a yoke 8, provided with lugs 9 and secured to the trolley pole 5 by means of the bolt 10.

Disposed is a yoke 11,

between the arms of the yoke S pivotally secured to the arms 0 the yoke 8 by means of the rod 12; The arms 13 of the yoke 11 are extended outward as at 1 1, and are curved with relation to the pole 5. Connecting the arms 13 at their outer ends, is a rod 15, on which is rotatably disposed a roller 16, preferably convex in shape. The arms 13 of the yoke extend to a point adjacent the wheel 6, and

the roller 16 is adapted to bear at all times a on the wire 7.

13 are provided with the into prevent the wire The arms tegral lugs 17 adapted 7 from passing between the wheels 6 and the arms 13 of the yoke. Connecting the arms 13 is a rod 18, to which is attached the trolley rope 19.

Connecting the arms 13 is a web 20, pro vided with a screw-threaded opening 21, in which is disposed a screw-threaded member 22, one end of which is adapted to bear against the under surface of the pole 5 and limit the movement of the yoke 11 towards the wire 7, and by means of which the range of this movement may be adjusted.

Formed on the upper edge of the on both sides thereof, are integral ugs 23, supporting a pintle 24:, which pintle carries a spring 25.

Provided in the spring 25 is a screwthreaded opening 26, in which is disposed a bolt 27 and on the bolt is disposed an adjusting nut 28. The end of the spring 25 is pivotally supported by the pintle 24:, so that the spring is free to work upward and downward, and the nut 28 is adapted to contact against the under face of the spring, and the end of the bolt 27 is adapted to contact against the under surface tension of the spring being adjusted by the bolt 30.

Connecting the arms 13 of the yoke adjacent its forward end, is a web 29, through which is disposed a bolt 30, for adjusting the tension of the spring 25. The forward en of the spring 25 is curved, as at 31, and its extreme end is concaved, as at 32, to fit closely the under surface of the pole 5.

One important function of my improved device is the protection of the trolley wire from receiving the full force of the shock incident to placing the trolley wheel on the wire. Owing to the spring pressure on the yoke 11, the roller 16 will normally rise somewhat above the wheel 6. Therefore, in

lacing the wheel on the wire, the first shock will be received by the roller 16, and mostly absorbed by the spring 25.

A further function of my device is to assist in maintaining a constant contact between the wheel and wire. By maintaining an additional spring pressed bearing point on the wire, the latter is steadied and prevented in a great measure from rapid vibration, which is mainl responsible for the trolley of the pole 5, the

what 0 aim as new Letters Patent is In combination yoke secured thereon, a second otall spring.

3. In combination with a trolley ole, a yoke secured thereon, and provided with inl lugs, a second yoke pivotally secured first yoke, and provided with curved arms, a roller on th t e second yoke, and means tension of the spring.

In combination yoke secured thereon, tegral lugs, a second yoke pivotally secured to the first yoke, and provided with curved outwardly expanded arms, a roller on the second yoke, a spring on the second yoke, and means for adjusting the tension of the spring.

5. In combination with a trolley pole, a yoke secured thereon, a second yoke pivfirst yoke, means for limiting the movement of spring.

11 combination with a trolley pole, a y ke secured thereon, a second yoke p otally secured with the first yoke, and pro-. vided with a connecting web having a screwthreaded opening therein, a second threaded member disposed through the opening and 4 for limiting the movement of the yoke, a spring pivotally secured to the provided with a screw-threaded opening, a screw-threaded member disposed through t e opening, and a screw-threaded member disposed through the web and adapted to contact against the spring.

11 combination with a trolley pole, a member pivotally connected with the pole, a roller carried by said member, means for limiting the movement of said curved spring pivotally secured to said memd means for varying the tension of the spring.

10. In combination with a trolley pole, a member pivotally connected with the pole, a roller carried by said member, means for limiting the movement of said member, a curved spring pivotally secured to said memer, an provided with a concaved end adapted to engage the trolley pole," and means for varying the tension of the spring.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
